Abstract

The invention relates to a novel sterilizing composition containing silthiopham. The sterilizing composition comprises an active component A and an active component B, wherein the active component A is selected from silthiopham; the active component B is selected from one of thiophanate-methyl and carbendazim; and the weight ratio of the effective active component A to the effective active component B is 1:80-60:1. After an auxiliary agent is added to the effective active components, the novel sterilizing composition can be prepared into wettable powder, water dispersible granules, suspending agents, suspension emulsion, water emulsion, microemulsion and used for controlling take-all disease of wheat, downy mildew, epidemic diseases, late blight, damping-off, powdery mildew, gray mold, early blight, fusarium wilt, sclerotinia, anthracnose, ring rot, penicilliosis and penicillium digitatum, is resistant in rain wash and has obviously synergic effect.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a novel bactericidal composition containing silthiocarb on crop diseases. technical background [0002] Silthiopham, English name: silthiopham, molecular formula: C 13 h 21 NOSSi, chemical name: N-allyl 4,5-dimethyl-2-trimethylsilthiophene-3-carboxamide. The mechanism of action of silthiofacillin is different from that of triazoles and methoxyacrylates. Studies have shown it to be an energy inhibitor: possibly an ATP inhibitor. It has good protective activity and long residual effect. Suitable crops and safety to crops Wheat, safe to crops, mammals, environment. Control object Wheat take-all disease. [0003] Regardless of whether it is silthiofacillin, effective active ingredient B or other high-efficiency fungicides, long-term use alone may easily cause disease resistance, leading to problems such as increased dosage, reduced control effect, and shorte...
